ok i know this question has been asked a thousand times before but i want a good opinion before i spend thousands of dollars to be disappointed. so im building my gsr. i plan on using:
jdm itr pistons .25mm over size
buddy club spec V cams, springs, retainers
buddy club p1 racing valves
full port and polish
upgraded fuel system (full rail, injectors, etc.)
12:1 compression (2 layer head gasket)
100 octane
bitchin tune
i havent decided i want to do with the crank or connecting rods yet. any ideas for those? wat kind of numbers can i get out of that. i want close to 250 to the wheels.

 

try the all motor forum...they might have better input

 

250whp aint happening without 2L and more compression

 

its hard to give an exact number.

you can put that same set up in 2 motors and one will make more power because no two motors are exactly the same

 

any ideas on what crank and rods i should use? and is this even a good setup?

 

have the stock crank balanced and micropolished. use stock rods with arp rod bolts since you're still using oem pistons. and dont forget to have the rods shaved to fit the itr pistons.

 

I'm no expert when it comes to cam selection but look into those cams a bit more. I think the BCV might be to aggresive for your setup.

And like doood said 250whp is not going to happen with that setup. You would need to PP the head, bore, stroke, and increase the compression along with using good quailty paired parts with a great tune.

Just to give you an idea this is a setup that put down around 230whp

spend the same on a turbo and make twice the power, but that's just my .02, either wal GL
